Correct master cylinder?

[dodgecharger-fan]

I have an XP 69 Charger that came from the factory with front disc brakes and a power booster.

The master cylinder has the line connections on the fender side. I've read that that's usually the case on a HEMI car only.

Now, I'm not thinking that I have a HEMI car, here. It's a 383 car, originally.
I'm just trying to get a clear understanding of what's considered correct.

It does not make sense that someone changed it out because that would have required changes to lines as well, right?
Or do you think it's possible?

I have my fender tag and a partial buildsheet.
I have parts books and a service manual.

I'm going to start digging in to those now, but I'd like to draw on the experience and knowledge here to get me going in the right direction.

Thanks.

I've attached a picture of my master cylinder

That is the Hemi style master (which for some reason is/was easier to get than the correct style that has the lines entering from the engine side)

Line replacement isnt totally necessary because all you have to do is massage them to twist a bit

Here is a pic of the correct master (which has become available from NAPA as a reproduction)

Here is a topic on the master

From my understanding they used that syle on 4 wheel power drums.

I thought all the disc brake ones had one resevoir larger than the other and drum brake systems had two the same?

[69_500]

Your right on the size of the resevoirs, but I think they were talking about what side the line connections are on? Or am I the one who is missing something here?

Drum brake master....power or manual

[Ghoste]

One of the mopar mags had a real good primer a couple of years ago on master cylinders that was written by somebody that had worked for one of the original suppliers.  I can't recall who or when though.  Mopar Action?

If it looks to be the factory installed unit then don't change it. (edit the following chart will helpdetermine orig or not)
Have them tested or rebuilt,or exchanged for a rebuilt unit.
The assembly line would not be stopped because of a different m/c and/or booster.
Parts shortages,different line workers all add up to some unique items on some cars.

Here's the article Ghoste mentioned.

Awesome Brian!   

[68charger383]

Any idea which color the all drum master should be painted. I did a search and here are two responses I found....but I'm still not sure: Also where's the best place to get the paint?

"If it was a power drum setup, then I think the correct booster is a Midland-Ross and it's gold cad.  I think the booster with these was natural cast iron."

"Drum brake cars the booster was left yellow zink dichromate with a natural master cylinder body is also unpainted"

Thanks

[Ghoste]

I thought all the factory master cylinders were unpainted?

[UFO]

In the photos of the road tests a lot of them look to be painted black.Its possible that the press pool cars were treated a little better(at least by the line workers).
I have painted mine my own mainly for some protection.I used eastwood co paints available in spray bombs.

[69_500]

I believe that regardless of brakes that they were all painted black.

[Ghoste]

I don't know.  A quick check on Paul Herds Charger Resoration Guide states they were all natural cast until 71 when some of them began to be painted gloss black.  I'm going to go through my photo album and look at some of the older pics and survivor cars.

So let me ask you guys this question, if you had manual drum brakes and you switched to manual front disk/rear drum brakes would you get the Hemi style master since the lines are routed the same (inner fender side) or would you switch to the 10-1475 Napa master with the lines on the engine side like Chris got?

[69_500]

Not to say that this is 100% correct of all cars built then, but this car is definately restored correctly in many many many aspects. And also the car had somewhere under 15,000 miles when restored and at that time it was painted black just like it is after being restored.

[69_500]

Then again these pictures are of 2 "survivor" Daytona's, and as you can see they aren't painted black. I will say this though, the one with manual brake, I will say for 90% that its not to me a survivor, it has had many minor repairs and freshining up over the years.

As you can see though in the second photo that there has also been some work, and replacing of parts done on the second one pictured. I believe that they have replaced the master cylinder in the second photo.

[gtx6970]

drum brake master are not painted , most are either a non-rusting coating or natrual as cast iron.

Every disc brake master I've seen is gloss black with the booster

[69_500]

Hey Bill, what color was the booster on the car we looked at about a month and a half ago? I didn't get a photo of it. As it wasn't in the car. Must have been on the floor somewhere and I somehow missed it.

[Ghoste]

I don't know that this is the original master cylinder in this car (which means I shouldn't post it) but I do know the car is unrestored.  It is disc brakes.

I don't remember seeing it either. Should be gloss bacl as mentioned

This is an unrestored 1970 S-bird a friend used to own

That picture is of a Charger 500 isn't it? I was looking at some shots of the engine compartment I have of that car as well. I'm going to dig up some of the magazine articles on that car from back in 68, but I'm pretty sure the top of the master cylinder was black in the magazine articles in the 68 year. Also notice that the washer bottle is a 80's repro.

[Ghoste]

Yeah, it was the only unrestored car that I already had pics of on my hard drive.  I've looked at a couple of magazine articles of it when new and they were no help.  In the b&w photos, one article it looks natural to me and the other looks black.
I'm going through my photo album looking for some survivor cars but so far I haven't found any underhood shots that help.  Even then, a survivor is just the same as the unrestored cars Bill and I have posted, they could easily have had the master replaced.  The disc master on my 67 was natural when I bought it but I am 99% certain that it wasn't the orginal so that doesn't prove squat either.
I'd like to know because my personal observation has been just the opposite of Bill, I have very rarely ever seen a black master cylinder on an old Mopar.  Doesn't mean anything, it is just what I've seen.  It's one of the things I really love about this sight though, the detective stuff.

[69_500]

I think that one of the main reasons that you don't ever see a black master cylinder on a car at a show, even a restored car is that people don't realize it is supposed to be painted black. I've went through all of the papers that I have, and I can't find the one that deals with power brake boosters. Apparently I took it out to look at and didn't put it back in order. As there is a gap for that section. But I'm almost 99.99% sure that they are supposed to be black, and for some reason I think its a slightly different black from the master cylinder to the power brake booster. I could be wrong on that one, maybe it just appears slightly different due to the booster being black, and the master cylinder being black painted over something is already coated.

[gtx6970]

I've yet to see an original disc brake booster / master cylinder assy that WASN"T gloss black- rule applies to 1970 and older btw

[UFO]

Thought I would post this pic just to throw the black or natural theory right out the window.
From a 67 GTX road test.

[69_500]

Just curious as to what road test that photo is from? It appears someone spray painted the booster and master cylinder as there is red overspray on the inner fender.

[Ghoste]

Yeah, looks like they oversprayed the wiper motor too.

So let me ask you guys this question, if you had manual drum brakes and you switched to manual front disk/rear drum brakes would you get the Hemi style master since the lines are routed the same (inner fender side) or would you switch to the 10-1475 Napa master with the lines on the engine side like Chris got?

Dammit! Someone shut my mic off again.

[Ghoste]

For me personally Bull, I'd leave the lines the way they were and get a master to fit if such was available.

[UFO]

69500 that is from -High performance cars feb 67- According to the article the two tone paint was not well done.Silver lower,red roof.Yes I would have to agree its done with a spray can.

Thanks. Now I need to figure that part number out.

[UFO]

If still on vehicle use a mirror to see the bottom casting number.
